The subject of this patent application relates generally to devices and methods for treating disorders using photobiomodulation therapy with near-infrared light.

By way of background, photobiomodulation therapy is the application of near-infrared light directed to various portions of a subject's body, for example, to the skin. Photobiomodulation therapy induces a photochemical reaction in the cells, increasing mitochondrial activity and ATP levels. The near-infrared light is calibrated to penetrate through the skin, soft tissue, cartilage, cerebrospinal fluid, and through bone structure for the purpose of providing treatment for various disorders. In an example transcranial photobiomodulation treatment, a near-infrared light source is directed to the head, such that the near-infrared light penetrates the skull to apply the light to the brain, for treating mental health related conditions like stress, fatigue, ADHD, other psychiatric, neuropsychiatric, and neurodegenerative diseases, and so on.

During treatment, one or more light source must be held in position on the user's skin for a prolonged period of time. However, the user may wish to continue with daily activities during the treatment period, requiring a portable system that remains in place during sedentary and vigorous activities, so that treatment is delivered accurately and without disturbance. Furthermore, a portable system would allow from immediate, real-time use enabling the user to undergo a photobiomodulation therapy whenever needed.

Aspects of the present invention fulfill these needs and provide further related advantages as described in the following summary.

A photobiomodulation therapy garment 20 also includes a photobiomodulation unit. A photobiomodulation unit includes a connection terminal, one or more near-infrared light sources, one or more sensors and is configured to establish electronic communication with controller 200. In some embodiments, and referring to FIGS. 8, 9 & 11 , a photobiomodulation unit 100 comprises a flexible printed circuit board assembly 110 that provides a flexible substrate housing the electrical circuitry which establishes electronic communication between a connection terminal 160 and one or more near-infrared light sources 170, such as, e.g., an infrared light, low-level laser, and/or light emitted diode (LED), one or more sensors 180, and optionally one or more stimulators 194. Connection terminal 160 (generally rigid or semirigid) includes an electronic circuity connector 162 mounted thereon, where electronic circuity connector 162 is configured to provide electronic communication between controller 200 and flexible printed circuit board assembly 110. In these embodiments, flexible printed circuit board assembly 110 is configured to provide flexibility and comfort to the wearer. For example, since photobiomodulation therapy headband 22 must closely match the contours of the forehead, flexible printed circuit board assembly 110 is designed with strategic cutouts to permit maximum flexibility and comfort. In some embodiments, and as shown in FIGS. 8 & 10 , flexible printed circuit board assembly 110 comprises a heat-dissipating material 102 on the flexible substrate on the side opposite the electrical circuitry that dispels heat generating by flexible printed circuit board assembly 110 during operation of photobiomodulation therapy garment 20.

In some embodiments, and referring to FIGS. 9 & 11 , flexible printed circuit board assembly 110 is a thin, flat substrate that includes a first surface and a second surface opposite the first surface and is configured as a main strip 112 which extends from connection terminal 160 and trifurcates at a root 113 into a first strip 114, a second strip 116, and a sensor strip 140 extending from the middle. First strip 114 and second strip 116 are connected distally by a connecting portion 117 and all define the bounds of cutout 118. First strip 114 and second strip 116 contain the electronic circuitry needed to establish electronic communication between each near-infrared light source 170 operationally mounted on first strip 114 or second strip 116 and connection terminal 160.

In some embodiments, first strip 114 and second strip 116 each include a series of tabs laterally extending outward therefrom, for mounting thereon near-infrared light sources disclosed herein. For example, as shown in FIGS. 9 & 11 , first strip 114 includes a first mounting portion 120, a second mounting portion 122, and a third mounting portion 124, with first mounting portion 120 separated from second mounting portion 122 by a first cutout 121 therebetween, and third mounting portion 124 separated from second mounting portion 122 by a second cutout 123 therebetween. Similarly, second strip 116 includes a first mounting portion 130, a second mounting portion 132, and a third mounting portion 134, with first mounting portion 130 separated from second mounting portion 132 by a first cutout 131 therebetween, and third mounting portion 134 separated from second mounting portion 132 by a second cutout 133 therebetween. First, second, third, mounting portions 120, 122, 124 of first strip 114 and first, second, third, mounting portions 130, 132, 134 of second strip 116 act like gores to permit independent flexible bending of flexible printed circuit board assembly 110. Such flexible bending enables flexible printed circuit board assembly 110 to easily conform to the contours of one or more regions of interest of skin region S and places each of the one or more near-infrared light sources disclosed herein in close proximity to skin surface S with minimal or no gap.

In some embodiments, and referring to FIGS. 9 & 11 , sensor strip 140 includes a sensor mounting portion 142 and a free end 144. Sensor strip 140 extends from root 113 into cutout 118 in a manner where cutout 118 provides clearance of sensor strip 140 from first strip 114 and second strip 116 such that sensor strip 140 is disconnected from first strip 114 and second strip 116 except at root 113. Sensor strip 140 contains the electronic circuitry needed to establish electronic communication between each sensor 180 operationally mounted on sensor strip 140 and connection terminal 160. Sensor strip 140 is relatively thin and elongated to permit bending and slight movement of sensor strip 140 relative to the remainder of flexible printed circuit board assembly 110, which is additionally permitted due to a sensor opening 224 provided by a double-sided tape 220 (see FIGS. 8, 15 , & 16), which permits easy bending and fitting about head H, with little or no kinks in flexible printed circuit board assembly 110.

In some embodiments, and referring to FIGS. 5, 8, 9, 11, 15 , & 16, integrally mounted to one end of flexible printed circuit board assembly 110 is connection terminal 160. Connection terminal 160 comprises electronic circuity connector 162 and a terminal rail mount 164. Electronic circuity connector 162 of connection terminal 160 is located on the same surface of flexible printed circuit board assembly 110 where one or more infrared light sources 170, one or more sensors 180, and one or more stimulators 194 are mounted and contains the electrical circuitry used to establish electronic communication with one or more infrared light sources 170, one or more sensors 180, and one or more stimulators 194. Terminal rail mount 164 of connection terminal 160 is located on flexible printed circuit board assembly 110 on the surface opposite of electronic circuity connector 162. Terminal rail mount 164 includes a plurality of contacts 166. Terminal rail mount 164 is configured to receive controller 200 and establish electronic communication between photobiomodulation unit 100 and controller 200 which has corresponding contacts that mate with contacts 166 when connected. To permit quick connection and disconnection, controller 200 and terminal rail mount 164 include sliding joinery (e.g., dovetail or tongue and groove like joinery) to capture controller 200 within terminal rail mount 164 and force electrical contact between contacts 166 of terminal rail mount 164 and corresponding contacts protruding though controller 200. After sliding controller 200 into terminal rail mount 164, controller strap 68 is wrapped over controller 200 and fastened to inside portion 44 of outer fabric sheet 40 by a releasable connection, such as hook and loop.

In some embodiments, and referring to FIGS. 15 & 16 , photobiomodulation unit 100 comprises a liquid wire circuit assembly 150 that provides electronic communication between connection terminal 160 and one or more near-infrared light sources 170, such as, e.g., an infrared light, low-level laser, and/or light emitted diode (LED), one or more sensors 180, and optionally one or more stimulators 194. A liquid wire comprises a type of metal that remains in the liquid phase at room temperature which is enclosed in a flexible tubing. Owing to its liquid phase nature, liquid metal can make good contact with objects in any shape and can maintain excellent electrical properties upon the deformation of the substrate or the covering film. Non-limiting examples of liquid metal include gallium and alloys such as eutectic gallium—indium. Liquid wire circuit assembly 150 includes connection terminal 160 with electronic circuity connector 162 mounted thereon, where electronic circuity connector 162 is configured to provide electrical communication between one or more liquid wire tubes of circuit assembly 150 and connection terminal 160. In these embodiments, liquid wire circuit assembly 150 is configured to provide flexibility and comfort to the wearer. For example, since photobiomodulation therapy headband 22 must closely match the contours of the forehead, liquid wire circuit assembly 150 is designed with strategic cutouts to permit maximum flexibility and comfort.

In some embodiments, and referring to FIGS. 15 & 16 , liquid wire circuit assembly 150 comprises a main liquid wire tube 152 which extends from connection terminal 160 and trifurcates at a root 153 into a first liquid wire tube 154, a second liquid wire tube 156, and a sensor liquid wire tube 158 extending from the middle affixed directly to an inner surface of outer fabric sheet 40. First and second liquid wire tubes 154, 156 contain the electronic circuitry needed to establish electrical connection between each near-infrared light source 170 operationally mounted to first or second liquid wire tubes 154, 156 and connection terminal 160 which, in turn provides electrical connection to controller 200. Sensor liquid wire tube 158 contains the electronic circuitry needed to establish electrical communication between each sensor 180 and/or each stimulator 194 operationally mounted to sensor liquid wire tube 158 and connection terminal 160 which, in turn provides electrical connection to controller 200. The affixing of first and second liquid wire tubes 154, 156 and sensor liquid wire tube 158 directly to an inner surface of outer fabric sheet 40 enables liquid wire circuit assembly 150 to easily conform to the contours of one or more regions of interest of skin region S and places each of the one or more near-infrared light sources disclosed herein in close proximity to skin surface S with minimal or no gap. Although not shown, liquid wire circuit assembly 150 can be configured in an arrangement similar to the arrangements shown for flexible printed circuit board assembly 110 of FIGS. 12-14 .

For example, in some embodiments, controller 200 operational controls one or more of the operation times of the one or more near-infrared light sources 170, the fluence level of the one or more near-infrared light sources 170, the irradiance level of the one or more near-infrared light sources 170, whether the one or more near-infrared light sources 170 are operated continuously or pulsed, which one or more of the one or more near-infrared light sources 170 are activated or deactivated, and predetermined dosimetry levels. In addition, controller 200 operationally controls each of the one or more sensors 180 and receives and analyzes information collected from each of the one or more sensors 180. In some embodiments, controller 200 operationally controls one or more of the operation times of the one or more stimulators 194, the power level of the one or more stimulators 194, whether the one or more stimulators 194 are operated continuously or pulsed, which one or more of the one or more stimulators 194 are activated or deactivated, or any combination thereof.

In some embodiments, controller 200 operationally instructs activating one or more infrared light sources 170 on the left side of midsagittal plane 320 and deactivating one or more infrared light sources 170 on the right side of midsagittal plane 320, or vice versa. In some embodiments, controller 200 operationally instructs activating one or more infrared light sources 170 on the left side and right side of midsagittal plane 320 while activating one or more infrared light sources 170 on the left side of midsagittal plane 320 at a higher level of irradiance relative to one or more infrared light sources 170 on the right side of midsagittal plane 320, or vice versa.

In some embodiments, controller 200 dynamically adjusts operational parameters of photobiomodulation therapy garment 20 using information collected from each of the one or more sensors 180, information provided by the user, or information remotely inputted by a third-party individual. Such information input is then processed by controller 200 relative to information stored in an operational database in one or more algorithms, and, based on the analysis performed in comparing collected or provided or inputted with information stored in such a database with the one or more algorithms, operational parameters of the one or more near-infrared light sources 170, each of the one or more sensors 180, and each of the one or more stimulators 194 are adjusted by executable instructions provided controller 200.

For example, cardiovascular sensor 182 obtains cardiovascular parameters from user during operation of photobiomodulation therapy garment 20 and this input information is analyzed against cardiovascular parameters stored in an operational database in order to assess actual cardiovascular parameters and adjust operation of photobiomodulation therapy garment 20 based on the therapy selected by the user or third-party individual. In some embodiments, a detected decrease in heart rate variability by cardiovascular sensor 182 and sent to controller 200 would result in controller 200 providing executable instructions to optimize the pulse wave by increasing the frequency of light emitted from the one or more near-infrared light source 170 in situations where a user or third-party individual has selected an alertness therapy. As an illustration, the initial pulse wave of photobiomodulation therapy garment 20 could be set at 40 Hz and based upon the detected heart rate variability controller 200 would increase the frequency of light emitted from the one or more near-infrared light source 170 to 50 Hz. Continuous monitoring and analysis of heart rate variability by cardiovascular sensor 182 and controller 200 could result in the 50 Hz pulse wave setting being maintained, or increased to 60 Hz or 70 Hz or more in order to establish the proper pulse wave for an alertness therapy being emitted from the one or more near-infrared light source 170. Such dynamic monitoring of heart rate variability by cardiovascular sensor 182 and controller 200 would result in continuous adjustments to the pulse wave in order to achieve optimum pulse wave of the selected alertness therapy.

In some embodiments, a detected increase in heart rate variability by cardiovascular sensor 182 and sent to controller 200 would result in controller 200 providing executable instructions to optimize the pulse wave by decreasing the frequency of light emitted from the one or more near-infrared light source 170 in situations where a user or third-party individual has selected a calmness or relaxation therapy. As an illustration, the initial pulse wave of photobiomodulation therapy garment 20 could be set at 40 Hz and based upon the detected heart rate variability controller 200 would decreasing the frequency of light emitted from the one or more near-infrared light source 170 to 30 Hz. Continuous monitoring and analysis of heart rate variability by cardiovascular sensor 182 and controller 200 could result in the 30 Hz pulse wave setting being maintained, or decreased to 10 Hz or 1 Hz in order to establish the proper pulse wave for a calmness or relaxation therapy being emitted from the one or more near-infrared light source 170. Such dynamic monitoring of heart rate variability by cardiovascular sensor 182 and controller 200 would result in continuous adjustments to the pulse wave in order to achieve optimum pulse wave of the selected calmness or relaxation therapy.

Such dynamic monitoring of skin temperature by skin sensor 192 and controller 200 would result in continuous adjustments to the irradiance in order to achieve optimum skin temperature of the selected alertness therapy.

Such dynamic monitoring of skin temperature by skin sensor 192 and controller 200 would result in continuous adjustments to the irradiance in order to achieve optimum skin temperature of the selected calmness or relaxation herapy.

In some embodiments, a detected decrease in skin temperature by skin sensor 192 and sent to controller 200 would result in controller 200 providing executable instructions to optimize skin temperature by increasing the duty cycle of light emitted from the one or more near-infrared light source 170 in situations where a user or third-party individual has selected an alertness therapy. As an illustration, the initial duty cycle of photobiomodulation therapy garment 20 could be set at 50% and based upon the detected skin temperature controller 200 would increase the duty cycle of light emitted from the one or more near-infrared light source 170 to 60%. Continuous monitoring and analysis of skin temperature by skin sensor 192 and controller 200 could result in the 60% duty cycle setting being maintained, or increased to 75% or more in order to establish the proper skin temperature for an alertness therapy. Such dynamic monitoring of skin temperature by skin sensor 192 and controller 200 would result in continuous adjustments to the duty cycle in order to achieve optimum skin temperature of the selected alertness therapy.

In some embodiments, a detected higher skin opacity, indicative skin with higher melanin content, by skin sensor 192 and sent to controller 200 would result in controller 200 providing executable instructions to optimize skin penetration by adjusting the wavelength of light emitted from the one or more near-infrared light source 170, or a combination of wavelengths, in order to provide optimal light penetration for the selected therapy. As an illustration, the initial wavelength of photobiomodulation therapy garment 20 could be set to 900 nm and based upon the detected skin opacity controller 200 would increase the wavelength of light emitted from the one or more near-infrared light source 170 to about 970 nm. Continuous monitoring and analysis of skin opacity by skin sensor 192 and controller 200 could result in the wavelength setting being maintained, or increased to 1000 nm or more in order to establish the proper wavelength penetration into the skin for the selected therapy. Such dynamic monitoring of skin opacity by skin sensor 192 and controller 200 would result in continuous adjustments to the wavelength in order to achieve optimum skin penetration of the selected therapy.

In some embodiments, a detected lower skin opacity, indicative skin with lower melanin content, by skin sensor 192 and sent to controller 200 would result in controller 200 providing executable instructions to optimize skin penetration by adjusting the wavelength of light emitted from the one or more near-infrared light source 170, or a combination of wavelengths, in order to provide optimal light penetration for the selected therapy. As an illustration, the initial wavelength of photobiomodulation therapy garment 20 could be set to 900 nm and based upon the detected skin opacity controller 200 would decrease the wavelength of light emitted from the one or more near-infrared light source 170 to about 810 nm. Continuous monitoring and analysis of skin opacity by skin sensor 192 and controller 200 could result in the wavelength setting being maintained, or decreased to 790 nm or less in order to establish the proper wavelength penetration into the skin for the selected therapy. Such dynamic monitoring of skin opacity by skin sensor 192 and controller 200 would result in continuous adjustments to the wavelength in order to achieve optimum skin penetration of the selected therapy.

In some embodiments, a detected higher skin density, indicative skin with higher fat content, by skin sensor 192 and sent to controller 200 would result in controller 200 providing executable instructions to optimize skin penetration by adjusting the wavelength of light emitted from the one or more near-infrared light source 170 in order to provide optimal light penetration for the selected therapy.

Continuous monitoring and analysis of skin density by skin sensor 192 and controller 200 could result in the wavelength setting being maintained, or decreased to 790 nm or less in order to establish the proper wavelength penetration into the skin for the selected therapy. Such dynamic monitoring of skin density by skin sensor 192 and controller 200 would result in continuous adjustments to the wavelength in order to achieve optimum skin penetration of the selected therapy.

As another example, information can be provided by a user or a third-party individual during operation of photobiomodulation therapy garment 20 and this input information is either used directly in order to adjust operation of photobiomodulation therapy garment 20 based on the therapy selected by the user, or analyzed against user-defined or third-party individual defined information stored in an operational database in order to adjust operation of photobiomodulation therapy garment 20 based on the selected therapy. As an illustration, the initial therapy of photobiomodulation therapy garment 20 could be set to an alertness therapy and based upon user input (such as, e.g., “still tired” or “feel good”) or individual third-party input (based upon, e.g., monitoring of physiological or vital signs of user) controller 200 would adjust the characteristics of the light being emitted from the one or more near-infrared light source 170. Continuous user or individual third-party input into controller 200 would establish the proper light characteristics for the selected alertness therapy. Such dynamic monitoring of user or individual third-party input into controller 200 would result in continuous adjustments to the light characteristics in order to achieve optimum effect of the selected alertness therapy.

As another example, sensor 180 obtains information on mitochondrial functionality from a user during operation of photobiomodulation therapy garment 20 and this input information is analyzed against mitochondrial functionality information stored in an operational database in order to assess actual mitochondrial functionality and adjust operation of photobiomodulation therapy garment 20 based on the therapy selected by the user or third-party individual. As an illustration, the initial therapy of photobiomodulation therapy garment 20 could be set to an alertness therapy and based upon detected mitochondrial functionality (such as, e.g., NAD⁺ or NADH levels) controller 200 would adjust the characteristics of the light being emitted from the one or more near-infrared light source 170. Continuous monitoring and analysis of skin opacity by sensor 180 and controller 200 would establish the proper light characteristics for the selected alertness therapy being emitted from the one or more near-infrared light source 170. Such dynamic monitoring of mitochondrial functionality by sensor 180 and controller 200 would result in continuous adjustments to the light characteristics in order to achieve optimum skin penetration of the selected alertness therapy.

The adjustments described in the examples in the paragraphs above made by the controller 200, and the processing performed therein on the various types of information, may be performed in conjunction with a machine learning-based framework that applies elements of artificial intelligence (AI) to analyze the information provided as input within models trained on historical or known data, such as that stored in the operational database(s) referenced above, to improve such adjustments to operational parameters of the one or more near-infrared light sources 170, each of the one or more sensors 180, and each of the one or more stimulators 194. The present invention therefore may include such a machine learning-based framework, which may be comprised of multiple elements that perform, either together or as separately-instantiated models, several of the processing aspects performed by the controller 200.

The modeling performed within the machine learning-based framework may comprise many different types of machine learning, and apply many different mathematical approaches to analyzing information and generating outputs that improve outcomes in the continuous adjustments to the operational parameters of the one or more near-infrared light sources 170, each of the one or more sensors 180, and each of the one or more stimulators 194 that are described herein. For example, in some embodiments of the present invention, the machine learning-based framework may be comprised of algorithms that apply techniques of supervised learning, reinforced learning, and other approaches of machine learning and artificial intelligence to further evaluate inputs into the controller 200.

The machine learning-based framework may be comprised of any of several different mathematical approaches. These may include statistical analyses, which are non-deterministic mathematical approaches that enable calculation of probabilities that events will or will not occur. Regression analyses are types of statistical analyses where models are used for estimating the relationships between variables of interest, such as for example a dependent variable and one or more independent variables (often called ‘predictors’). This type of machine learning is used to infer causal relationships between the independent and dependent variables, and for prediction and forecasting of outcomes where such causal relationships are impactful on future states for application of the overall modeling being performed. There are many types of regression analyses, such as linear and non-linear regression, and specific approaches such as logistic regression, that enable the use of derived parameters to interpret the importance of maximum values in form of the log-odds when calculating probability values. For example, other types of logistic functions, and other types of regression analyses, may also be utilized to calculate probabilities in the present invention, and are within the scope of the present invention. Other approaches that may be utilized include, but are not limited to, decision trees, random forest classifiers, support vector machines, and probit. It is therefore to be further understood that the present invention, and the present specification, are not to be limited to any one type of mathematical model or statistical process mentioned herein, particularly as to its application in the one or more layers of machine learning.

Modeling within the machine learning-based framework may also include applications of neural networks. Neural networks generally are comprised of nodes, which are computational units having one or more biased input/output connections. Such biased connections act as transfer (or activation) functions that combine inputs and outputs in some way. Nodes are organized into multiple layers that form the neural network. There are many types of neural networks, which are computing systems that “learn” to perform tasks, without being programmed with task-specific rules, based on examples.

Neural networks generally are based on arrays of connected, aggregated nodes (or, “neurons”) that transmit signals to each other in the multiple layers over the biased input/output connections. Connections, as noted above, are activation or transfer functions which “fire” these nodes and combine inputs according to mathematical equations or formulas. Different types of neural networks generally have different configurations of these layers of connected, aggregated nodes, but they can generally be described as an input layer, a middle or ‘hidden’ layer, and an output layer. These layers may perform different transformations on their various inputs, using different mathematical calculations or functions.

Signals are transmitted between nodes over connections, and the output of each node is calculated in a non-linear function that sums all of the inputs to that node. Weight matrices and biases are typically applied to each node, and each connection, and these weights and biases are adjusted as the neural network processes inputs and transmits them across the nodes and connections. These weights represent increases or decreases in the strength of a signal at a particular connection. Additionally, nodes may have a threshold, such that a signal is sent only if the aggregated output at that node crosses that threshold. Weights generally represent how long an activation function takes, while biases represent when, in time, such a function starts; together, they help gradients minimize over time. At least in the case of weights, they can be initialized and change (i.e., decay) over time, as a system learns what weights should be, and how they should be adjusted. In other words, neural networks evolve as they learn, and the mathematical formulas and functions that comprise neural networks design can change over time as a system improves itself.

The application of neural networks within the machine learning-based framework may include instantiations of different networks for different purposes. These include both “production” neural network(s), configured to refine the algorithms performed within the overall modeling framework to generate output data (for example, as adjusted operational parameters of the one or more near-infrared light sources 170, each of the one or more sensors 180, and each of the one or more stimulators 194), and “training” neural network(s), configured to train the production network(s) using improvements on the reasons for prior, historical outcomes that have been learned.

Recurrent neural networks are a name given to types of neural networks in which connections between nodes follow a directed temporal sequence, allowing the neural network to model temporal dynamic behavior and process sequences of inputs of variable length. These types of neural networks are deployed where there is a need for recognizing, and/or acting on, such sequences. As with neural networks generally, there are many types of recurrent neural networks.

Neural networks having a recurrent architecture may also have stored, or controlled, internal states which permit storage under direct control of the neural network, making them more suitable for inputs having a temporal nature. This storage may be in the form of connections or gates which act as time delays or feedback loops that permit a node or connection to retain data that is prior in time for modeling such temporal dynamic behavior. Such controlled internal states are referred to as gated states or gated memory, and are part of long short-term memory networks (LSTMs) and gated recurrent units (GRUs), which are names of different types of recurrent neural network architectures. This type of neural network design is utilized where desired outputs of a system are motivated by the need for memory, as storage, and as noted above, where the system is designed for processing inputs that are comprised of timed data sequences. Examples of such timed data sequences include video, speech recognition, and handwriting—where processing requires an analysis of data that changes temporally. In the present invention, where output data is in the form of operational parameters of the one or more near-infrared light sources 170, each of the one or more sensors 180, and each of the one or more stimulators 194, an understanding of the influence of various events on a state over a period of time lead to more highly accurate and reliable operational parameters that may at least impact an amount of time that stimulation is provided.

Many other types of recurrent neural networks exist. These include, for example, fully recurrent neural networks, Hopfield networks, bi-directional associative memory networks, echo state networks, neural Turing machines, and many others, all of which exhibit the ability to model temporal dynamic behavior. Any instantiation of such neural networks in the present invention may include one or more of these types, and it is to be understood that neural networks applied within the machine learning-based framework may include different ones of such types. Therefore, the present invention contemplates that many types of neural networks may be implemented, depending at least on the type of problem being analyzed

Controller 200 reversibly connects to photobiomodulation therapy garment 20 by operationally engaging terminal rail mount 164. Controller 200 may optionally include a rechargeable battery positioned within the housing. Controller 200 can be detached from terminal rail mount 164 for charging the rechargeable battery therein, by using a charging connector, such as USB-C, micro-USB, or the like. Further, the charging connector can provide wired data communication with a remote computer, such as a smart phone, laptop, desktop, or other computer device. In one or more embodiments, this enables tracking of usage, and/or updating or changing operational parameters such as desired dosimetry, duration, pulsed operation, etc., and/or to update the controller firmware, and/or to change the type of photobiomodulation therapy garment 20 to which controller 200 will be attached. Controller 200 can be a universal controller, such that controller 200 can be connected to multiple embodiments of photobiomodulation therapy garment 20, such as photobiomodulation therapy headband 22, a neck region garment, a posterior cervical region garment, a carpal region garment, an abdominal region garment, and the like, each being configured to cover their respective regions when donned.

Each near-infrared light source groupings is spaced apart from the neighboring groupings, where the intergroup spacing can be the same between each near-infrared light source grouping or can vary according to the desired dosimetry and vary according to the relative locations of the desired regions of interest. The relative pattern of near-infrared light source groupings is configured to position each grouping on photobiomodulation therapy garment 20 to at least partially cover their respective regions of interest on skin surface S, which may appear to be a random pattern to the casual observer. The spacing of an intergroup pattern between each near-infrared light source grouping can be defined by a column distance d1 and by a row distance d2. The intergroup distance can be measured from the centers of the light sources. In one or more embodiments, column distance d1 and row distance d2 are at least 5 mm, or at least 10 mm, or at least 15 mm, or at least 20 mm, or at least 25 mm, or at least 30 mm, or at least 35 mm, or at least 40 mm. In a rectangular array, row distance d2 can be the same distance or differ from column distance d1.

First, second and third near-infrared light source groupings 171, 172, 173 are positioned to cover a region containing sites F3 306, Fz 308 and F4 310 of head H. Fourth near-infrared light source grouping 174 is positioned to cover a region containing sites Fp1 300 and fifth near-infrared light source grouping 175 is positioned to cover a region containing sites Fp2 304. In these embodiments, one or more sensors 180 are located in the lower row and are positioned below second near-infrared light source grouping 172 and in between fourth near-infrared light source grouping 174 and fifth near-infrared light source grouping 175.

In some embodiments, and as shown in FIG. 14 , photobiomodulation unit 100 comprises three near-infrared light source groupings of near-infrared light source 170, namely first near-infrared light source grouping 171, second near-infrared light source grouping 172, and third near-infrared light source grouping 173. First, second, and third near-infrared light source groupings 171, 172, 173, are aligned in a row and are positioned to cover a region containing sites F3 306, Fz 308 and F4 310 of head H. In these embodiments, one or more sensors 180 are positioned below second near-infrared light source grouping 172.

In some embodiments, each of near-infrared light source groupings comprises a single light near-infrared light source 170. For example, and as shown in FIGS. 11-14 & 16 , each of near-infrared light source groupings 171, 172, 173, 174, 175, 176 of photobiomodulation unit 100 comprises a single light near-infrared light source 170. In embodiments where only a single light near-infrared light source 170 is present in a near-infrared light source grouping, such near-infrared light source 170 is preferably a high-powered near-infrared light source having a radiant intensity (brightness) range of about 150 mW/sr or more, and more preferably about 250 mW/sr or more.

In some embodiments, each of near-infrared light source groupings comprises a plurality light near-infrared light sources 170. For example, and as shown in FIGS. 9 & 15 , each of near-infrared light source groupings 171, 172, 173, 174, 175, 176 of photobiomodulation unit 100 comprises nine light near-infrared light sources 170. In embodiments where a plurality light near-infrared light sources 170 is present in a near-infrared light source grouping, such near-infrared light source 170 can all be low-powered near-infrared light source having a radiant intensity (brightness) range of 125 mW/sr or less. In other embodiments where a plurality light near-infrared light sources 170 is present in a near-infrared light source grouping, such near-infrared light source 170 can all be a combination of both high-powered near-infrared light source having a radiant intensity (brightness) range of about 150 mW/sr or more, and more preferably about 250 mW/sr or more and low-powered near-infrared light source having a radiant intensity (brightness) range of 125 mW/sr or less.

Additionally, in embodiments where a near-infrared light source grouping comprises a plurality light near-infrared light sources 170, there is an intragroup spacing between each individual near-infrared light source 170 and the neighboring near-infrared light sources 170 within the same group. The intragroup spacing of each near-infrared light source 170 of an a near-infrared light intragrouping can be the same between each individual near-infrared light source 170 or can vary according to the desired dosimetry and vary according to the relative locations of the desired regions of interest. In some embodiments, each individual near-infrared light source 170 of each of near-infrared light source grouping is arranged in a pattern configured for desired therapeutic effect, with each individual near-infrared light source 170 being randomly relative to the other individual near-infrared light sources 170 within the same near-infrared light source group, and/or in a pattern determined by a combination of factors including a desired therapeutic effect, cost, manufacturing capabilities, and so on. The relative pattern of near-infrared light source groupings is configured to position each near-infrared light source 170 on photobiomodulation therapy garment 20 to at least partially cover their respective regions of interest on skin surface S, which may appear to be a random pattern to the casual observer.

Each individual near-infrared light source 170 within a near-infrared light intragrouping is spaced from all other individual near-infrared light sources 170 within the same intragrouping by an intragroup light source spacing. Each near-infrared light source 170 in a near-infrared light intragrouping can be arranged in a pattern that matches the location of multiple regions of interest on skin surface S. Thus, the resulting near-infrared light intragrouping can seemingly be arranged in irregular patterns that correspond to the location of multiple regions of interest on skin surface S, where each can be simultaneously at least partially covered by a corresponding grouping. As a result, the intergroup spacing and relative positioning of each near-infrared light source 170 in a near-infrared light intragrouping can vary according to the locations of the regions of interest on skin surface S.

In some embodiments, for example in a rectangular arrangement as shown in FIG. 3 , the spacing between each near-infrared light source 170 of a near-infrared light intragrouping can be defined by a column spacing d3 and by a row spacing d4. The intragroup spacing can be measured from the centers of the near-infrared light source 170. In some embodiments, column spacing d3 and row spacing d4 are at least 2 mm, at least 3 mm, at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8mm, at least 9 mm, at least 10 mm, at least 12 mm, or at least 15 mm. In a rectangular array, row spacing d3 can be the same distance or differ from column spacing d4. In such rectangular arrangement, each near-infrared light source 170 of a near-infrared light intragrouping is arranged in a n1×n2 array, where n1 and n2 each represent the number of individual near-infrared light sources 170 in a row and column, respectively. For example, an infrared light intragrouping can be a 2×2 array, a 2×3 array, a 3×2 array, a 3×3 array, a 3×4 array, a 4×3 array, a 4×4 array, a 2×5 array, a 5×2 array, a 3×5 array, a 5×3 array, a 4×5 array, a 5×4 array, a 5×5 array, and so on. In some embodiments, each near-infrared light source 170 of a near-infrared light intragrouping can be configured as a radial or circular array about a single circle or multiple concentric circles. In these embodiments, an intergroup spacing can be measured from the centers of the light sources.

In some embodiments, each of near-infrared light source of photobiomodulation therapy garment 20 is configured as near-infrared light intragrouping comprising a plurality of near-infrared light sources 170 arranged in an intragroup array. In some embodiments, near-infrared light source groups 171, 172, 173, 174, 175, 176 of photobiomodulation therapy garment 20 are each configured as near-infrared light intragrouping comprising a plurality of near-infrared light sources 170 arranged in an intragroup array, with first near-infrared light source group 171 comprising a plurality of near-infrared light sources 170 arranged in a first near-infrared light intragrouping, second near-infrared light source group 172 comprising a plurality of near-infrared light sources 170 arranged in a second near-infrared light intragrouping, third near-infrared light source group 173 comprising a plurality of near-infrared light sources 170 arranged in a third near-infrared light intragrouping, fourth near-infrared light source group 174 comprising a plurality of near-infrared light sources 170 arranged in a fourth near-infrared light intragrouping, fifth near-infrared light source group 175 comprising a plurality of near-infrared light sources 170 arranged in a fifth near-infrared light intragrouping, and sixth near-infrared light source group 176 comprising a plurality of near-infrared light sources 170 arranged in a sixth near-infrared light intragrouping.

In some embodiments, and referring to FIGS. 3, 9 , & 12, near-infrared light source groupings 171, 172, 173, 174, 175, 176 of photobiomodulation therapy headband 22 are each configured as near-infrared light intragrouping comprising nine near-infrared light sources 170 arranged in a 3×3 array of three columns and three rows. In this example, d3 is greater than d4, which can create therapeutic benefits due to the combined and overlapping light patterns incident on skin surface S surface, as well as strategic gaps or areas of lesser overlap of light patterns. In the illustrated example embodiment, d3=6 mm to 7 mm and d4=9 mm to 10 mm. The overlapping pattern of incident light creates regions of varying power levels incident on skin surface S within and around each array or grouping, with areas of maximum irradiance and fluence immediately beneath each individual near-infrared light source 170, areas of lesser irradiance and fluence between closely situated individual near-infrared light sources 170, and areas of least irradiance and fluence between individual near-infrared light sources 170 situated furthest from one another. Additionally, although each near-infrared light intragrouping of near-infrared light source groupings 171, 172, 173, 174, 175, 176 is each illustrated as having the same intragroup pattern, each intragroup pattern can be configured with differing patterns and numbers of individual near-infrared light sources 170, which can be determined based on the desired form of therapy and the dosimetry required for each region of interest.

In one or more embodiments, in operation, groupings of near-infrared light sources can all be activated by controller 200 using the same operational parameters (e.g., all groupings simultaneously activated, all in pulsed mode, and all with the same power settings). In one or more embodiments, in operation, groupings of near-infrared light sources can each be activated by controller 200 with differing operational parameters, where one or more selected groupings may be activated, while other groupings remain off. Further, in one or more embodiments, controller 200 has capabilities to control the power level and/or pulsed/continuous operation for each grouping of near-infrared light sources independent of other groupings of near-infrared light sources on photobiomodulation therapy garment 20. There is a great deal of flexibility in operational parameters available. Not only can each individual grouping of near-infrared lights be individually operated, each individual near-infrared light source 170 in each grouping of near-infrared lights can be individually addressed and controlled using individual operating parameters. In this way, each individual near-infrared light source 170 can be individually addressable as a unit such that each can activated/turned on or deactivated/turned off independent of all other individual near-infrared light sources 170. Further, in one or more embodiments, each individual near-infrared light source 170 can be actuated in a pulsed or continuous mode independent of all other individual near-infrared light sources 170. Additionally, in one or more embodiments, each individual near-infrared light source 170 can be actuated using a power profile independent of all other individual light sources. In this way, a number of predefined patterns can be initiated via executable instructions from controller 200, where the patterns of activated light sources can change according to the desired therapeutic effect and location of regions of interests.

Looking now at FIGS. 8, 15 & 16 , in some embodiments, photobiomodulation therapy garment 20 is assembled by sandwiching photobiomodulation unit 100 between outer fabric sheet 40 and inner fabric sheet 70. In some embodiments, and as shown in FIG. 8 , a hot melt adhesive film 210, sized and shaped to cover a substantial portion or all of flexible printed circuit board assembly 110, but not to cover terminal rail mount 164 of connection terminal 160, is positioned between outer fabric sheet 40 and photobiomodulation unit 100. In some embodiments, and as shown in FIGS. 15 & 16 , liquid wire circuit assembly 150 is affixed directly to outer fabric sheet 40, e.g., by using an adhesive or weaving into outer fabric sheet 40.

In embodiments where photobiomodulation unit 100 comprises liquid wire circuit assembly 150, connection terminal 160 is affixed to outer fabric sheet 40 during construction of liquid wire circuit assembly 150 onto outer fabric sheet 40.

Still referring to FIGS. 8, 15 & 16 , once photobiomodulation unit 100 is position on outer fabric sheet 40, a layer of double-sided tape 220, sized and shaped to cover a substantial portion or all of photobiomodulation unit 100, is positioned between photobiomodulation unit 100 and inner fabric sheet 70. Double-sided tape 220 includes one or more near infrared light source openings 222 and one or more sensor openings 224, each being cutouts configured to provide clearance for their respective components, such that double-sided tape 220 does not interfere with the operation of the one or more near-infrared light sources 170 and one or more sensors 180. If present, sensor cover 79 is properly positioned over its corresponding sensor 180. Inner fabric sheet 70 is then aligned with outer fabric sheet 40 and photobiomodulation unit 100 and positioned so that each of the one or more near-infrared light sources 170 and each of the one or more sensors 180 is properly positioned with their corresponding near infrared light source opening 76 and sensor opening 78 thereby permitting proper functioning of these components. Inner fabric sheet 70 can then be secured to outer fabric sheet 40 by sewing the edges of inner fabric sheet 70 to outer fabric sheet 40.

A photobiomodulation therapy garment disclosed herein is useful in providing a photobiomodulation therapy, including a transcranial photobiomoculation therapy. Such non-invasive light-based neuromodulation treatment requires no medication and provides long-lasting benefits by changing how a user's brain works from the neuron-level up by providing a variety of positive photochemical reactions. For example, a photobiomodulation therapy can increase neuronal mitochondria energy and adenosine triphosphate (ATP) production resulting in increased production of cellular energy. In addition, transfer of light energy can also trigger reactive oxygen species (ROS) production, which can regulate cellular and tissue-level inflammation and improve cellular repair and healing, and nitric oxide (NO) production which is critical for good blood vessel health and optimal blood flow, nutrient delivery and waste removal. This is important as inadequate cerebral blood flow and circulation can make the brain experience fuzzy memory, forgetfulness, poor concentration and even dementia. Enhanced cellular energy and increased cerebral blood flow result in increased neurogenesis and neuronal plasticity, increased neuroprotection, enhanced neural repair, and reduced inflammation. In addition, such photobiomodulation therapy provides both calming and relaxation benefits as well as improved focus and performance resulting in enhanced mental productivity, mental wellbeing and overall cognitive function.

Example 6 tPBM Treatment Increases Functional Conductivity of Neurons

A research study was conducted to assess the neuronal conductivity effects of a transcranial photobiomodulation (tPBM) treatment using a photobiomodulation therapy garment disclosed herein. Each participant underwent an EEG analysis for 8 minutes before a tPBM treatment in order to establish a baseline. Each participant was then administered tPBM treatments using a photobiomodulation therapy garment disclosed herein. Each tPBM treatment was bilateral and applied to the frontal areas with two application sites on the left side, two on the right side and two on the midline [left, right and center forehead on the frontal EEG sites on F3, Fpl, F4, Fp2 and Fz, Fpz]. Once accurate placement is ensured, a tPBM treatment was initiated by a button press on a specific phone application to activate the probes delivering the LED light. The duration of irradiation was 40 min per treatment. The tPBM treatment followed these specifications: the energy was administered with a radiation wavelength of 850 nm, the irradiance (IR) was 18 mW/cm²; the fluence was up to 43 Joules/cm²; the energy delivered per session was up to 2.4 kJ; and each treatment window area was 55 cm². After completion of the tPBM treatment, each participant underwent a second EEG analysis for 8 minutes.

The results of this research study showed that participants exhibiting increased functional connectivity of their neurons (as measured with EEG activity) compared to sham. For example, FIGS. 17A-C shows the results of five (5) participants. Scans of the EEG analysis conducted after the tPPB treatment exhibit focused points of light (FIG. 17B) as compared to scans taken before the tPBM treatment (FIG. 17A). These differences are further underscored by FIG. 17C, which illustrates the focused light of the before and after scans. These findings is indicative of improved connections between neurons. Increased functional connectivity allow neurons to transmit information faster and more accurately. The results were reproducible and not evident with the sham.

Example 7 tPBM Treatment Increases Brain Activity

A research study was conducted to assess brain activity effects of a transcranial photobiomodulation (tPBM) treatment using a photobiomodulation therapy garment disclosed herein. Each participant underwent an EEG analysis for 8 minutes before a tPBM treatment in order to establish a baseline. Each participant was then administered tPBM treatments using a photobiomodulation therapy garment disclosed herein. Each tPBM treatment was bilateral and applied to the frontal areas with two application sites on the left side, two on the right side and two on the midline [left, right and center forehead on the frontal EEG sites on F3, Fpl, F4, Fp2 and Fz, Fpz]. Once accurate placement is ensured, a tPBM treatment was initiated by a button press on a specific phone application to activate the probes delivering the LED light. The duration of irradiation was 40 min per treatment. The tPBM treatment followed these specifications: the energy was administered with a radiation wavelength of 850 nm, the irradiance (IR) was 18 mW/cm² ; the fluence was up to 43 Joules/cm²; the energy delivered per session was up to 2.4 kJ; and each treatment window area was 55 cm². After completion of the tPBM treatment, each participant underwent a second EEG analysis for 8 minutes.

The results of this research study showed that participants exhibited increased brain gamma oscillation increased during a 40 Hz pulse wave therapy compared to sham. For example, FIGS. 18A-18B shows a representative result from one participant. As shown in FIG. 18A by the shaded block, there was a significant increase of over 35% in brain gamma oscillations at a frequency of 40 Hz. In addition, as shown in FIG. 18B, there is a significant peak of gamma power between about 250 seconds to about about 350 seconds, at which point gamma power levels decline but are maintained at a higher level as compared to baseline gamma power levels. These findings are indicative of brain gamma wave stimulation which underlie many cognitive operations including perception. Increased brain gamma wave stimulation promotes brain activity to transmit information faster and more accurately. The results were reproducible and not evident with the sham.

Example 8 tPBM Treatment for Depression in Adults

An 8-week open-label pilot clinical study was conducted to assess the safety, and efficacy of a tPBM treatment using a photobiomodulation therapy garment disclosed herein in adults with active depressive symptoms. The study enrolled 19 participants clinically diagnosed with moderate to severe depressive symptoms according to the Beck's Depressive Inventory (BDI, baseline score of 25).

Participants were administered tPBM treatments twice daily at home for 8 weeks using a photobiomodulation therapy garment disclosed herein. Each tPBM treatment was bilateral and applied to the frontal areas with two application sites on the left side, two on the right side and two on the midline [left, right and center forehead on the frontal EEG sites on F3, Fpl, F4, Fp2 and Fz, Fpz]. Once accurate placement is ensured, a tPBM treatment was initiated by a button press on a specific phone application to activate the probes delivering the LED light. The duration of irradiation was 40 min per treatment. The tPBM treatment will follow these specifications: the energy will be administered with a radiation wavelength of 850 nm, the irradiance (IR) will be 18 mW/cm²; the fluence will be up to 43 Joules/cm²; the energy delivered per session will be up to 2.4 kJ; and each treatment window area will be 55 cm².

At the end of the 8-week clinical study of tPBM treatment of depression using a photobiomodulation therapy garment disclosed herein, investigators detected a significant reduction in depressive symptoms among participants. For example, participants experienced a 43% decrease in depressive symptoms at week 8 as assessed by the Beck's Depression Inventory. The finding was a statistically significant change from baseline (significance p=0.001). Interestingly, the improvement was maintained for at least 4 weeks after stopping the tPBM treatment. In fact, at week 12 the investigators still detected an average decrease of 48% in depressive symptoms, compared to baseline, as assessed by the Beck's Depression Inventory. The finding was also a significant change from baseline (significance p<0.0001). Subsequent analyses revealed that the improvements in depression were at least partially explained by improvement in sleep quality.

Example 9 tPBM Treatment for Pediatric Depression

An 8-week open-label pilot clinical study will be conducted to assess the safety, and efficacy of a tPBM treatment using a photobiomodulation therapy garment disclosed herein in children with active depressive symptoms as assessed through the Child Behavior Checklist (CBCL). The study will enroll 20-30 participants, ages 6 to 17 years, who currently experience a CBCL T score of 60 or higher on the Anxious/Depressed scale. Each participant will be clinically assessed by completing a series of clinical intake questionnaires and scales, including 1) CBCL, a parent-report questionnaire that evaluates maladaptive behavioral and emotional problems, both internalizing and externalizing, in children ages 6-18; 2) the Pediatric Quality Of Life Enjoyment and Satisfaction Questionnaire (PQ-LES-Q), a 15 question parent-report form designed to help assess the degree of enjoyment and satisfaction the child is experiencing during the past week; 3) the Behavior Rating Inventory of Executive Function-Parent Report (BRIEF-P), a 78-item rating scale to assess level of executive function deficits; and 4) the Social Responsiveness Scale (SRS), a 65-item rating scale completed by the parent used to measure social deficits as they occur in natural settings.

Participants will be administered daily tPBM treatments for 8 weeks. tPBM treatment will use a photobiomodulation therapy garment disclosed herein will be bilateral and applied to the frontal areas with two application sites on the left side, two on the right side and two on the midline [left, right and center forehead on the frontal EEG sites on F3, Fpl, F4, Fp2 and Fz, Fpz]. Once accurate placement is ensured, a tPBM treatment will be initiated by a button press on a specific phone application to activate the probes delivering the LED light. The duration of irradiation will start at 10 min per treatment for the first week (days 1-7), increase to 20 min per treatment during the second week of treatment (days 7-14) and to 30 min per treatment at week 3 (days 14-21) of treatment. If side-effects prevent increase (or if treatment response already occurred), a lower dose will be kept in order to ensure good tolerability and treatment adherence. At day 21, the clinician will recommend 40 min daily treatment if no improvement in the context of good tolerability. The tPBM treatment will follow these specifications: the energy will be administered with a radiation wavelength of 850 nm, the irradiance (IR) will be 18 mW/cm² ; the fluence will be up to 43 Joules/cm²; the energy delivered per session will be up to 2.4 kJ; and each treatment window area will be 55 cm².

Subjects will be evaluated at weekly intervals for the first four weeks, and biweekly thereafter. At each visit, measures of safety and efficacy will be obtained using assessments of psychiatric symptoms and functioning and measures of adverse effects. At the midpoint (end of week 4) and final study visits (week 8 or Endpoint), additional clinician-and subject-rated assessments will be completed. Response to treatment will be assessed by the following assessment measures 1) a Clinician completed Depression Specific Clinical Global Impression (CGI-Depression), including Clinical Global Severity (CGI-S), Clinical Global Improvement (CGI-I), and the CGI-Efficacy Index (CGI-EI) Scale, will be completed by the physician at every visit; 2) an Affective Reactivity Index-Parent Report (ARI-P), a concise, 7 question parent-report form assessing irritability and temper, will be completed by the parent at week 0 (baseline), week 4 and week 8; 3) a Childhood Anxiety Sensitivity Index (CASI-Anx), a 38-item scale that assesses symptoms of anxiety, will be completed by the parent at week 0 (baseline), week 4 and week 8; and 4) a Children's Depression Inventory (CDI), a 27-item scale that assesses symptoms of depression, will be completed by the parent at week 0 (baseline), week 4 and week 8.

The results are expected to show that a tPBM treatment will be safe and effective in reducing symptoms of pediatric depression.

In closing, foregoing descriptions of embodiments of the present invention have been presented for the purposes of illustration and description. It is to be understood that, although aspects of the present invention are highlighted by referring to specific embodiments, one skilled in the art will readily appreciate that these described embodiments are only illustrative of the principles comprising the present invention. As such, the specific embodiments are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Therefore, it should be understood that embodiments of the disclosed subject matter are in no way limited to a particular element, compound, composition, component, article, apparatus, methodology, use, protocol, step, and/or limitation described herein, unless expressly stated as such.

In addition, groupings of alternative embodiments, elements, steps and/or limitations of the present invention are not to be construed as limitations. Each such grouping may be referred to and claimed individually or in any combination with other groupings disclosed herein. It is anticipated that one or more alternative embodiments, elements, steps and/or limitations of a grouping may be included in, or deleted from, the grouping for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is deemed to contain the grouping as modified, thus fulfilling the written description of all Markush groups used in the appended claims.

Furthermore, those of ordinary skill in the art will recognize that certain changes, modifications, permutations, alterations, additions, subtractions and sub-combinations thereof can be made in accordance with the teachings herein without departing from the spirit of the present invention. Furthermore, it is intended that the following appended claims and claims hereafter introduced are interpreted to include all such changes, modifications, permutations, alterations, additions, subtractions and sub-combinations as are within their true spirit and scope. Accordingly, the scope of the present invention is not to be limited to that precisely as shown and described by this specification.

Certain embodiments of the present invention are described herein, including the best mode known to the inventors for carrying out the invention. Of course, variations on these described embodiments will become apparent to those of ordinary skill in the art upon reading the foregoing description. The inventor expects skilled artisans to employ such variations as appropriate, and the inventors intend for the present invention to be practiced otherwise than specifically described herein. Accordingly, this invention includes all modifications and equivalents of the subject matter recited in the claims appended hereto as permitted by applicable law. Moreover, any combination of the above-described embodiments in all possible variations thereof is encompassed by the invention unless otherwise indicated herein or otherwise clearly contradicted by context.

The words, language, and terminology used in this specification is for the purpose of describing particular embodiments, elements, steps and/or limitations only and is not intended to limit the scope of the present invention, which is defined solely by the claims. In addition, such words, language, and terminology are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification structure, material or acts beyond the scope of the commonly defined meanings. Thus, if an element, step or limitation can be understood in the context of this specification as including more than one meaning, then its use in a claim must be understood as being generic to all possible meanings supported by the specification and by the word itself.

The definitions and meanings of the elements, steps or limitations recited in a claim set forth below are, therefore, defined in this specification to include not only the combination of elements, steps or limitations which are literally set forth, but all equivalent structure, material or acts for performing substantially the same function in substantially the same way to obtain substantially the same result. In this sense it is therefore contemplated that an equivalent substitution of two or more elements, steps or limitations may be made for any one of the elements, steps or limitations in a claim set forth below or that a single element, step or limitation may be substituted for two or more elements, steps or limitations in such a claim. Although elements, steps or limitations may be described above as acting in certain combinations and even initially claimed as such, it is to be expressly understood that one or more elements, steps or limitations from a claimed combination can in some cases be excised from the combination and that the claimed combination may be directed to a sub-combination or variation of a sub-combination. As such, notwithstanding the fact that the elements, steps and/or limitations of a claim are set forth below in a certain combination, it must be expressly understood that the invention includes other combinations of fewer, more or different elements, steps and/or limitations, which are disclosed in above even when not initially claimed in such combinations. Furthermore, insubstantial changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalently within the scope of the claims. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. Accordingly, the claims are thus to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be obviously substituted and also what essentially incorporates the essential idea of the invention.

Unless otherwise indicated, all numbers expressing a characteristic, item, quantity, parameter, property, term, and so forth used in the present specification and claims are to be understood as being modified in all instances by the term “about.” As used herein, the term “about” means that the characteristic, item, quantity, parameter, property, or term so qualified encompasses a range of plus or minus ten percent above and below the value of the stated characteristic, item, quantity, parameter, property, or term. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary. For instance, as mass spectrometry instruments can vary slightly in determining the mass of a given analyte, the term “about” in the context of the mass of an ion or the mass/charge ratio of an ion refers to +/−0.50 atomic mass unit. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical indication should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.

Notwithstanding that the numerical ranges and values setting forth the broad scope of the invention are approximations, the numerical ranges and values set forth in the specific examples are reported as precisely as possible. Any numerical range or value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Recitation of numerical ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate numerical value falling within the range. Unless otherwise indicated herein, each individual value of a numerical range is incorporated into the present specification as if it were individually recited herein.

Use of the terms “may” or “can” in reference to an embodiment or aspect of an embodiment also carries with it the alternative meaning of “may not” or “cannot.” As such, if the present specification discloses that an embodiment or an aspect of an embodiment may be or can be included as part of the inventive subject matter, then the negative limitation or exclusionary proviso is also explicitly meant, meaning that an embodiment or an aspect of an embodiment may not be or cannot be included as part of the inventive subject matter. In a similar manner, use of the term “optionally” in reference to an embodiment or aspect of an embodiment means that such embodiment or aspect of the embodiment may be included as part of the inventive subject matter or may not be included as part of the inventive subject matter. Whether such a negative limitation or exclusionary proviso applies will be based on whether the negative limitation or exclusionary proviso is recited in the claimed subject matter.

The terms “a,” “an,” “the” and similar references used in the context of describing the present invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. Further, ordinal indicators—such as, e.g., “first,” “second,” “third,” etc.—for identified elements are used to distinguish between the elements, and do not indicate or imply a required or limited number of such elements, and do not indicate a particular position or order of such elements unless otherwise specifically stated. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples or exemplary language (e.g., “such as”) provided herein is intended merely to better illuminate the present invention and does not pose a limitation on the scope of the invention otherwise claimed. No language in the present specification should be construed as indicating any non-claimed element essential to the practice of the invention.

When used in the claims, whether as filed or added per amendment, the open-ended transitional term “comprising”, variations thereof such as, e.g., “comprise” and “comprises”, and equivalent open-ended transitional phrases thereof like “including,” “containing” and “having”, encompass all the expressly recited elements, limitations, steps, integers, and/or features alone or in combination with unrecited subject matter; the named elements, limitations, steps, integers, and/or features are essential, but other unnamed elements, limitations, steps, integers, and/or features may be added and still form a construct within the scope of the claim. Specific embodiments disclosed herein may be further limited in the claims using the closed-ended transitional phrases “consisting of” or “consisting essentially of” (or variations thereof such as, e.g., “consist of”, “consists of”, “consist essentially of”, and “consists essentially of”) in lieu of or as an amendment for “comprising.” When used in the claims, whether as filed or added per amendment, the closed-ended transitional phrase “consisting of” excludes any element, limitation, step, integer, or feature not expressly recited in the claims. The closed-ended transitional phrase “consisting essentially of” limits the scope of a claim to the expressly recited elements, limitations, steps, integers, and/or features and any other elements, limitations, steps, integers, and/or features that do not materially affect the basic and novel characteristic(s) of the claimed subject matter. Thus, the meaning of the open-ended transitional phrase “comprising” is being defined as encompassing all the specifically recited elements, limitations, steps and/or features as well as any optional, additional unspecified ones. The meaning of the closed-ended transitional phrase “consisting of” is being defined as only including those elements, limitations, steps, integers, and/or features specifically recited in the claim, whereas the meaning of the closed-ended transitional phrase “consisting essentially of” is being defined as only including those elements, limitations, steps, integers, and/or features specifically recited in the claim and those elements, limitations, steps, integers, and/or features that do not materially affect the basic and novel characteristic(s) of the claimed subject matter. Therefore, the open-ended transitional phrase “comprising” (and equivalent open-ended transitional phrases thereof) includes within its meaning, as a limiting case, claimed subject matter specified by the closed-ended transitional phrases “consisting of” or “consisting essentially of.” As such, the embodiments described herein or so claimed with the phrase “comprising” expressly and unambiguously provide description, enablement, and support for the phrases “consisting essentially of” and “consisting of.”

Lastly, all patents, patent publications, and other references cited and identified in the present specification are individually and expressly incorporated herein by reference in their entirety for the purpose of describing and disclosing, for example, the compositions and methodologies described in such publications that might be used in connection with the present invention. These publications are provided solely for their disclosure prior to the filing date of the present application. Nothing in this regard is or should be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention or for any other reason. All statements as to the date or representation as to the contents of these documents are based on the information available to the applicant and do not constitute any admission as to the correctness of the dates or contents of these documents.
